MARKIN MACHINE.

Application filed larch 20, 1925. Serial No. i7,119.

This invention relates to marking machines and more particularly to such ma-:

chines in which there is an operator-controlled setting device to enable the ready:

interchange of the markers.

Marking machines are extensively used in shoe factories for marking the various portions of the upper and for this pur ose are usually provided with a plurality o adjustable markers in the form of rotatable disks 7 arranged side by side which may carry the printing type faces directly upon their toothed peripheries or may be mechanically connected to other wheels which do carry the type faces.

characters imprinted commonly is arranged to indicate such things as the case number, the style of shoe, the size, width, etc. While marking machines of the same type are used 7 for many other purposes and to. impress a great variety of characters, the example noted will serve for the discussion of the presentinvention, although it will be understood that the invention is not limited to any particular use or to the illustrated marking organization. 1

Such machines frequently require the resetting of the markers between every operation and, to enable the o erator to set the 0 marker carrying rotatab e disks or other members without bringing the hands into direct contact therewith, setting devices have commonly been provided having operating handles. To enable the easy use of such a setting device it is common to provide looking means rest-raining all but'one of the markers in order that the operator may not disturb markers which itis desired not to change.

'In view of the foregoing, an object of the present invention is 'to'provide a marking machine organization having improved type retaining and setting devices by the use of which the release and adjustment of one or more selected markers may be still further facilitated.

Looking toward the fulfillment of this object and in accordance with a feature of the invention, the illustrated machine has a setting device carried by a sliding frame which is supported for positioning movement transversel of a marking head carrying a pluralit 0 7 adjustable markers mounted side by si e; In the illustrated arrange- When thus used, the row of ment the adjustable markers are in the form formed upon the ends of the teeth on their peripheries, and the disks are mounted for rotation on a cylindrical support. and are provided with notches on their inner peri heries. A notched locking bar is mounte in the slidin frame in engagement with the notches o the various disks so that all the disks save the one which isopposite to the notch in said bar are locked against rotation. A manually operated setting device having a star wheel is mounted on said frame in corresponding relation to the notch of'the lock- 7 ing bar and preferably an index deviceis provided upon the frame toindicate uickl to the operator both the particular dis wit which the setting device is in co-operative relation and the type face on said disk which 15 1n prlnting position. i

Still another feature of the invention consists in the provision of means in addition and half-size marks. Such anarra'ngement is particularly desirable because of the necessity of changing the size disks more often than the other disks are changed and in the illustrated arrangement an independent setting device is arranged in engagement with these two disks arranged to move-them. together step by stepto'print the whole sues," cession of size and half-size numbers or; separately if desired. Because of much greater use of these particular disks they are so mounted that they are inde endent of the locking bar which controls t e other disks 7 of the markin head. V a I r This and ot er features of the invention will be more readily understood from a con-. sideration of the following specification taken in connection with the accompanying drawings, in which:

Fig. 1 is a side elevation of one form of marking machine to which a marking head provided with my improved setting device has been applied; Fig. 2 is a transverse vertical section through the marking head on the line 2-2 of Fig. 1; p

withandlaway fi'oinfthe work. The support 20 isguidedlfor movement. in parallel planes by means ofa parallel arm 30 pivoted in themachine frame at 32 and pivotally attached to tlieupper end of. the support 20 at. 3 1-. An inkingroll 36 is arranged to carry ink from an inking-supply 1 'oll 38 to the type faces and'this inking roll is carried on the end of an arm 4-0 pivotally mounted in the frame of the machine and actuated by, a. link 42from an extension 44 .on the parallel arm 30.; A rodjel6 connected to the bell crank lever 28. passes through the end offthe table-locking arm 16 which is normally held in locking position by'means' of a spring 48'surrounding the rod 46. As the head is carried. into marking position, however, the enlarged end50 of the rod 46 raises the table-locking arm 16' and allows automatic adjustment of the table under the tension of a spring 52 and the pressure of the marking head upon the work carried by the; tabl'e so that. said pressure is unitorm regardless ofithe number of layers of work carried thereby.

Themarking head is supported bet-ween "thespacedside hangers 22fand 2% by means ofjia cylindricalsupport 50 carried by said hangers and made hollow to reduce ts weight, This-hollow support '50 has a pair of internal enlargements, one of wh ch is. prOVlCl.Cl;W1tli a SLUtZLblQ recess 53 for the reception of an electrically heated cartridge un1t-.5 1-. A guideway 56' is providedrin the otheit enl'argement. and is located in the periphery of the cylindrical support for a {purpose to be later explained. iEot-ataloly mounted upon the support are a plurality of adjustable, markers in the form of annular disks 60, which, in the present in-.

stance, are provided with. toothed peripheries having type faces upon the ends of the teeth. Each, of these disks is provided uponits inner periphery. with a plurality of'notclies 62 for the reception of alocl-zing bar 64; slidaloly mounted. in. the gnideway "56 extending longitudinally ofthe external disks'in the head;

periphery of the cylindrical; support. As

- will be noted from Fig. 4 the locking bar is provided with a notch 66 which, in the present instance,.isshown as being. of the width.

of one of the disks... By means of thisarrangement all but one of the disks. isheld in locked position upon the support while the particular disk which is opposite to the notch 66 on the bar '64- maybe turned to bring thedesired type face into printing po sition. The locking bar 64 forms part of a sliding frame made up with lateral mem bers 68 and 70 which are joined at the front by a transverse bar 72- carrying an index finger 73 which is positioned opposite the notch 66 of the bar64 and thus indicates tothe operator which disk is released for adjustment. At the rear of' the frame a rod 74 is pivotally mounted in the frame and passes through bosses upon the hangers 22 and 24, a fragment of one of these being indicated at'76 in Fig. 3. V is provided upon this rod 74 andsecured star wheel SOindicates visually to the operator that d sk whiehis released andmay be set, because it is positioned uponithe rod vided-to allow the rotation of'the disk which is opposite to the notch 66 by rotating the star wheel 80. As will beseen from Fig. 2, a ball latch 84 is providedin the side member 70 of the sliding frame and this latch is adapted to engage. suitable. recesses 86 (Flg. ina head 88 carried .at the other to hold the star Wheel impositively in markerdisk has one .ofits type faces in ahnement with the row of types to. be im- I pressed on the work.

lVhen a marking machine of this type is used for shoe work, it commonly will be provided with a pair of. disks 106 and 11 0 hav ingtypefaces to indicate sizes on one of. the disksll0 and, half sizes upon. the other disk A setting" device thereto, which, in the present instance, takes the form ofa star wheel 80 arranged for engagement with'the teeth of any one of the lvhether or not the 'in- .dexfinger 73 is used, the position of this .7 directly opposite to the notch 66v ofthe i bar 64. .An operating handle 82 is proendof the lOCl'l'l. This latch is intended .the position in .which. the corresponding 106. These disks have enough: type faces on their peripherlesso that, when they are moved'jtogetlier stepby step, they may be caused to print the whole successionof. size and half-size. numbers.v In. thev illustrated arrangement a setting Wheel 90 carriedupon a rod. 92 pivoted in thehangers '22and' 24 isIarranged: at a point intermediatev between twosuchdisksso that. it-engages both of the disks and turns themtogether whenmanipulatedi byv means of anoperating, handle 94.

Because of'themuch greater use of't-hese particular disks, they are made independent.

ofthe lockingbar 64 by making them freely with suita le recesses 100'which are adapted to be engaged by. the rounded end of a plunger 102 pressed outwardly by means of a,

spring 104. This latching arrangement serves a similar purpose as does the latch 84 but it also performs additional functions. When it is desired to move the setting wheel to thefright to bring it into engagement with only the half-size disk 106, the operator is able tomove the rod 92 carrying this setting wheel'to the right against the tension of the retaining spring 104 by grasping the operating handle 94. To this end sufficient clearance is provided between the .head 98 and a boss 108'upon the hanger 22 in which the latch is mounted. When, on the other hand, the operator desires to turn only the size wheel 110, the setting wheel 90 may be moved to the left after a notchedspacing lever 112 pivoted upon the hanger 24 and provided with a forwardly extending handle has beenlifted to allow the operating handle 94 to approach more closely the side of the hanger 24. The tension of the spring 104, acting through the plungerlatch 102, will then be sufficient to move the setting wheel 90 into alinement with the size disk 110.

In the operation of the setting devices the size disks will be controlled by'turning the operating handle 94 while the other diskswill be controlled, to bring the desired markers into operative position, by slidin the frame carrying the locking. bar 64 laterally. until theindex finger 73 is positioned in alinement with the particular disk which it is desired to change. The operating handle 82 may then be rotated toset this disk, which, it will be remembered, is released because of the coincidence therewith of the 'notch 66 upon the bar 64.

The operation of the machine is controlled by means of a suitable clutch (not shown) under the control of which the head-carrying support 20 is moved up and down to bring thelowennost row of typefaces upon the marking head into and out of engagement with the work carried upon the work table 10. As the marking head starts on its downward movement, the inking roll 36 will be carried across the row of type faces together with any type upon a name plate 120, if such a plate is being used, and during the continued movement of the marking head the inking roll will be brought into engagement with the ink-supplying roll 38 while the markers are engaging the work upon the table. As the marking head returns again to its upper position, the inking roll will return to the position shown in Fig.

1 and supply ink to the type faces. The operation of the automatic work-supporting table 10 is-well understood in the art. When the marking head is depressed, locking device 16 is released just prior to the engagement ofthe work by the marking head so that the table is pressed against the under side of the work under the tension of a spring 52 with the result that the pressure 1 of the marking head upon the work is substantially uniform regardless of the number ofpieces of work carried by the table. As soon as the marking head starts upward, the locking device 16. is again brought into engagement with the shank of the table 10 and held there b tension of the spring 48.
